plant and remote transmitter. When operating out of re-
quirements, the link cannot guarantee error free trans-
mission.
The AFBR-57J7APZ optical transceiver is made of metal
and high strength, heat resistant, chemical resistant and
UL 94V-0 flame retardant plastic.
Fault Isolation
Predictive Failure Identification
The fault isolation feature allows a host to quickly
pinpoint the location of a link failure, minimizing
downtime. For optical links, the ability to identify a fault
at a local device, remote device or cable plant is crucial to
speeding service of an installation. AFBR-57J7APZ real-
time monitors of Tx_Bias, Tx_Power, Vcc, Temperature and
Rx_Power can be used to assess local transceiver current
operating conditions. In addition, status flags Tx_Disable
and Rx Loss of Signal (LOS) are mirrored in memory and
available via the two-wire serial interface.
The AFBR-57J7APZ predictive failure feature allows a host
to identify potential link problems before system perfor-
mance is impacted. Prior identification of link problems
enables a host to service an application via “fail over”
to a redundant link or replace a suspect device, main-
taining system uptime in the process. For applications
where ultra-high system uptime is required, a digital SFP
provides a means to monitor two real-time laser metrics
associated with observing laser degradation and pre-
dicting failure: average laser bias current (Tx_Bias) and
average laser optical power (Tx_Power).
Component Monitoring
Compliance Prediction:
Component evaluation is a more casual use of the
AFBR-57J7APZ real-time monitors of Tx_Bias, Tx_Power,
Vcc, Temperature and Rx_Power. Potential uses are as
debugging aids for system installation and design, and
transceiver parametric evaluation for factory or field qual-
ification. For example, temperature per module can be
observed in high density applications to facilitate thermal
evaluation of blades, PCI cards and systems.
Compliance prediction is the ability to determine if an
optical transceiver is operating within its operating and
environmental requirements. AFBR-57J7APZ devices
provide real-time access to transceiver internal supply
voltage and temperature, allowing a host to identify
potential component compliance issues. Received optical
power is also available to assess compliance of a cable
